CARTRIDGE Original Filed Aug. 21, 1936 IN VEN TOR.

ATTORNEY Patented June 11, 1940 UNITED STATES PATENT OFFICE Application August 21, 1936, Serial No. 9?,227 Renewed November 30, 1938 1 Claim. '(01; 102-12) This invention relates to cartridges, or similar devices. for use with gas generating chemicals of the kind which produce poisonous, irritating or disabling gases.

One of the objects of this invention is to expose a large area of the heat andpressure generating and igniting chemicals to the gas generating chemicals in the cartridge.

Another object of the invention is to entirely 1 separate the heat and pressure generating chemicals from the gas producing chemicals in the cartridge.

Yet another object of this invention is to provide a cartridge with a conoidal receptacle which u contains the heat and pressure generating agents.

Still another object of this invention is to provide a cartridge which rapidly produces gases, when fired.

A further object of this invention is to provide a cartridge with a conoidal container for the heat and pressure generating chemicals which is held in proper position when in loaded condition.

u A still further object of this invention is to provide a cartridge in which either solid or liq uid gas generating chemicals may be used and which is exposed to a large area of heat and pressure generating chemicals.

Still another object of this invention is to load cartridges with a uniform quantity of heat and pressure generating chemicals and a uniform quantity of gas generating agents without the aid of measuring devices.

To the accomplishment of these and such other objects as may hereafter appear the invention consists of the novel construction. combination and arrangement of parts herein specified and illustrated in the accompanying drawing. where- 4 in are shown several embodiments of the invention. but it is to be understood that changes.

variations and modifications may be resorted to which come within the scope of the claim hereunto appended.

In the drawing wherein like numerals of reference designate corresponding parts throughout the several views.

Figure 1 is a horizontal sectional view of one form of a cartridge, illustrating a flanged co- 0 noida] container which holds propellent chemnoidal receptacle provided at its bottom with a cylindrical rim or cup in addition to the flange illustrated in Figure 1.

Figure 3 illustrates a horizontal sectional view of another modified form of a cartridge in which the conoidal container fits snugly around the I primer socket.

Figure 4 shows a horizontal sectional view of a modification of a cartridge using a sealed container charged with liquid gas generating chemicals which is provided with a conoidal entrant or bottom adapted to be filled with propellent chemicals.

Figure 5 is a horizontal sectional view of a modification of a cartridge, partly-broken away, in which the conoidal receptacle is provided at ll its bottom with a flared end.

Referring to Figure 1 of the drawing, there is shown a cartridge shell 6 comprising an elongated cylindrical casing I having a closed end 8 provided with an inwardly projecting primer socket 30 which has a central aperture 3| for the reception of the usual primer 9. Within said casing "I is placed a combustible conoidal receptacle ll which is provided with an outwardly flanged end ll of slightly lesser diameter than the inside diameter of said casing I, so as to permitentrance in said casing.

This conoidal container or receptacle III is filled to the flange II, and the bottom l2 of the casing I is covered slightly over the inner end of the primer socket 3|! with a propellent charge l3, so as to form an uninterrupted mass when in loaded condition.

A charge of gas generating chemicals H is then placed in the casing l, as shown, thus completely surrounding the conoidal container III with thesame and at the same time completely separating the heat and, pressure generating chemicals from the gas generating chemicals in said casing I. 40

Over the charge of the gas generating chemicals ll in casing I is the usual wad l5 and above this wad is a disk ii of waterproof material which is provided with a central depression H. the latter serving as a means to centrally retain the conoidal container in said casing I.

A cupped disc l8 serves as a seal after the edge 19 of said casing? 1 has been finally turned over, as shown.

The modified form of the cartridge shown in 5 Figure 2 is substantially similar to that of Figure 1. with the exception that the flange 20 of the conoidal container 2| is extended to form a circular rim 22, the edge of which will rest on the bottom I! of thecasing I when assembled, as

thus avoiding double filling of the propellent charge, as is the case in the construction illustrated in Figure 1.

The cartridge illustrated in Figure 3 discloses a conoidal container 23 which slides over the primer socket 30 which contains the primer 9.

In Figure 4 there is shown a cartridge in which liquid gas generating chemicals 24 are used and the container 25 for the same is made from Celluloid or other suitable material and the same is provided with an inwardly disposed conoidal depression 26, which is intended for a purpose as the conoidal containers previously described.

After the said container. is charged with gas generating chemicals, the same is provided with a cover 32 having a tip 21 serving as a centering means when in final position. To prevent leakage the cover 32 is hermetically sealed to the container 25.

Figure 5 shows another modification of a cartridge, in this case the conoidal receptacle, 28 is provided with a flared end 29 which rests on the bottom 12 of casing 1, when in assembled position.

On discharge of any one of the above described cartridges, the ignition is transmitted from the primer 9 to the propellent chemicals I! through aperture 3! of the primer socket and the intense heat and pressure will melt or burn the conoidal container which holds the gas generating chemicals II and because of the large area to which said container is exposed the gas or gases will be rapidly evolved and violently liberated.

I claim:

'In a cartridge of the character described, a

' casing open at one end; a primer socket positioned in the-other end of said casing and having an aperture leading within said casing; a primer within said primer socket; a conoidal container of combustible material in said casing having a pointed, closed apex and an open base, and filled with a propellent charge; means to centrally retain the open end of said conoidal container at the bottom of said casing with its RExanUm'ER.
